I am happy to recommend ASSIST. It was quite difficult for us to find someone who would help us move away from an archaic system (we had too many different systems), but it turns out that ASSIST is pretty flexible and easy to use. I think that if you're already an enterprise business owner, you should look into this! Assist's customer service has been excellent as far as getting through my technical questions quickly, and providing good answers when I ask them. They've also been very helpful regarding moving things around in my accounts section so that everything works better together.
